5.10.1 DISTRESS CALL AND POSITION REQUEST
During a distress situation, a vessel that is equipped with a DSC VHF radio
and connected to a GPS, has the capability to transmit a DSC Distress Call with GPS
Position.
When the VHF radio receives a DSC Distress Call, the position information
of the vessel in distress is transferred to the chart plotter. The chart plotter logs the
Distress Call into the DSC Log and also marks the position of the vessel in distress
on the Chart page. A pop-up screen advises the user that a Distress Call has been
received. Within the pop-up screen it asks the user if he would like to view the call on
the Chart page or exit the pop-up screen. By selecting the item "VIEW ON CHART"
and press 'ENTER' two options are shown:
• GoTo Vessel
Activates the navigation to the Distress Call or Position Request icon. The
chart plotter changes the map scale to allow showing the Distress Call (or
Position Request) icon and the vessel’s icon simultaneously on the screen.
The chart plotter then verifies if there are obstructions (land or low water)
between the two positions. If obstructions are found the chart plotter shows
a pop-up screen saying that the navigation to the Distress Call cannot be set
automatically and the user must define a route to avoid the obstacles.
• Stay on View
Exits the pop-up screen and remains on the selected map screen.
